I don’t know where Dygenguar is from other than one of the Super Robot Wars games, but this box for Kotobukiya’s 1/144 Dygenguar model is bigger than any 1/144 kit that I’ve seen save the massive HGUC 1/144 Dendrobium. Check out the detailing on the face.
So it’s way too late to buy this thing as an X-Mas present for your favorite mech head, but you could hand over a bag of cash so that he (read: me) can buy it from HobbyLink Japan for ¥29,800 ($334.31 USD). No idea how tall he stands once complete, but I bet it towers over any Gundam HGUC 1/144 kit. *drooooool*
